Grainger, Percy Aldridge (1882-1961), was an Australian-born composer and pianist. His best-known compositions are based on the folk music of England, Scotland, and Ireland. Among these is Molly on the Shore in versions for orchestra, small orchestra, strings, and piano. His choral works include Green Bushes, Marching Song of Democracy, and Tribute to Foster. Grainger was also a music experimenter. For example, his Free Music for Theremin uses one of the earliest electronic instruments. Grainger's music has become popular with wind bands.
